Bergman delves into psychologically disturbing material. The closest he ever came to making a horror film. Avante-garde cinema at its finest. How much of it is in our character’s minds and how much is reality? This is explored throughout. Bergman loves tapping into the unconscious and pulling out unpleasant fears and anxieties. After all, hour of the wolf relates to that darkest hour of the night where the worst crimes are committed.
